Unfortunately, fsquirt won't work as Apple has purposefully disabled
bluetooth file transfers, apparently, in an attempt to limit user choices.

One option, of course, is to use Apple's trojan bloatware replacement for
the deprecated and insecurely defunct iTunes abomination, which is here:
 *Install the Apple Devices app on Windows*
 <https://support.apple.com/guide/devices-windows/install-the-apple-devices-app-mchl5ded2763/windows>

Since every thread should add value, here's more information about the
Apple Devices for Windows" program, which maybe replaces iTunes.
 <https://apple-devices.en.uptodown.com/windows>
 "This program is designed to allow you to use Apple devices 
  on Windows without having to rely on iTunes as before.
  Apple Devices's interface is very simple and minimalistic;
  all you have to do is connect your Apple device to your PC
  with a USB cable. Once connected, Apple Devices will recognize
  the Apple device, and you'll be able to manage all its content 
  and functions from Windows."

Since we're actually trying to solve the problem of how to copy a photo
from Windows to an iOS device, it behooves us to find a working solution.

Apparently "Documents by Readdle" has a free tier that I will try.
 <https://apps.apple.com/us/app/documents-file-manager-docs/id364901807>

Also, SMB Manager - CIFS Client seems like it might copy a photo over.
 <https://apps.apple.com/us/app/smb-manager-cifs-client/id1141340577>

Likewise, "LAN drive SAMBA Server Client" might copy a photo to the iPad.
 <https://apps.apple.com/us/app/lan-drive-samba-server-client/id1317727404>

But those are clients, I think - but maybe they're also SMB servers? 
With respect to SMB servers versus SMB clients, note this distinction.
 For iOS to receive a file from a Windows PC, you need an iOS SMB server.
 For iOS to retrieve a file from a Windows PC, you need an SMB client.
 (i.e., the server pitches the file to the other device)

If SMB doesn't work, another option is to turn the Windows PC into a
temporary local HTTPS/WEBDAV web server to host the photo for iOS.

One such local web server is "HFS HTTP File Server" which is found here.
 <https://sourceforge.net/projects/hfs/>
 Name: hfs2.3m.zip
 Size: 947592 bytes (925 KiB)
 SHA256: 5B99A22785D90BE6CB39C58E59C89514CC394152AD0BC83FDB5F56A7AD08E05E
When extracted, there is only a single file in the archive:
 Name: hfs.exe
 Size: 2171904 bytes (2121 KiB)
 SHA256: E678899D7EA9702184167B56655F91A69F8A0BDC9DF65612762252C053C2CD7C

Right now, I'm gonna try that hfs solution, where I'll let you all know
what works as it behooves us to be able to copy a file from Windows to iOS.

In summary, I'll solve this problem, but it would be nice if someone else
on this newsgroup has copied a photo from Windows to the iPad before me.

Good news. Bad news.

The good news is that we can now easily circumvent all of Apple's absurd
restrictions on copying a photo from Windows to the iOS device using HFS.
 *Tutorial: How to copy a photo from Window to iOS without Apple restrictions*
 <https://www.novabbs.com/computers/article-flat.php?id=19950&group=misc.phone.mobile.iphone#19950>

The bad news is that Steve (and I) were wrong that iOS allows screenshots
when the app being screenshotted doesn't want to allow those screenshots.

I just now tested whether Windows mirroring of iOS screens via Vysor
would be able to capture the protected screenshots from the cartoonifiers.

The unfortunate answer is that even iOS is now protecting its screenshots.
Vysor does NOT show the image even as the image shows up on the iPad.
  <https://i.postimg.cc/7LssFdjb/vysor-ios.jpg>

In case you're wondering, even the iPad native screenshot mechanism won't
capture that image, even as you can *see* it - but it won't capture it.

So, I don't blame Steve, but he's wrong (and so was I) as iOS no longer
allows the Vysor screen mirroring app to take screenshots of the screen
when it's protected by the app (which in my tests was the Voila app).
iOS "Voila"
 <https://apps.apple.com/us/app/voil%C3%A0-ai-artist-cartoon-ghibli/id1558421405>
Android "Voila"
 <https://play.google.com/store/apps/details?id=com.wemagineai.voila>

Steve maintains a wonderfully comprehensive document on the differences
between iOS and Android, which I suggest he updates to add this datum.

You can see here, that as a mechanism is discovered, it is blocked.

  https://www.reddit.com/r/hacking/comments/rsuh5b/anyone_know_a_working_bypass_for_cant_screenshot/?rdt=36016

It's no different than the protections that Windows has for certain things.
Anything that Microsoft wants... isn't protected :-)

And it's not even called "Recall" either.

Thanks for that link. I'm sure there's a way to screenshot anything (e.g.,
a camera will always work so it's really not worth them blocking it).

Apparently the primary way Android apps prevent screenshots on Windows is
by setting the FLAG_SECURE window flag in Android. This flag tells the
Android operating system to block any attempts to capture the screen
content.

It used to be different before (oh, about Android 11) but now, when I use
Windows scrcpy or Vysor mirroring software (mostly scrcpy nowadays), the
scrcpy software shows a black screen, as they noted in that reddit thread.

A rooted Android can disable the "FLAG_SECURE" but my Galaxy bootloader
version is not known to be rootable. However, the thread does suggest we
could just drop down to an older Android version (which would work).

Some suggested browser-based or screen-recording solutions, but cartooning
is app based and I doubt a simple screen recording app will work, but it
might if I can find an open-source screenrec that ignores FLAG_SECURE.

There was a suggestion that a virtual Android VM on Windows might work,
especially if we drop it down to the older Android version, so that's the
most feasible suggestion in that thread I've seen so far as I read it.

The general consensus in the thread is that there isn't yet a single,
reliable, and easy method to bypass screenshot prevention enforced by
FLAG_SECURE without resorting to complex workarounds like rooting or using
external cameras. But that has never stopped us before, so why stop now?

Interesting since I can't use Windows 11 on my 2009 desktop (which was
beefy at the time it was born) but CoPilot was thrust onto my system
recently. 

Apparently, from that thread, Copilot in Windows 11 will gain the ability
to "see what you see" on your screen, which is an OCR of sorts by M$.

Thanks for that datum about CoPilot "seeing" what's on your screen.

> And it's not even called "Recall" either.

I didn't understand that comment until I googled what "recall" is to M$.

Apparently "Recall" is a new feature in Windows 11, specifically designed
for Copilot+ PCs which acts as a "photographic memory" for your activity.

Apparently it has continuous screenshots, local storage & analysis, a
timeline of your activities, an automatic click to do feature, and a
natural language search of your activities (which your wife will love!).

Apparently it only works on Copilot+ PCs, which, again, I had to google
since I have a Copilot- PC (built in 2009) where apparently nowadays
Windows 11 PCs have a Natural Processing Unit (NPU) for AI (which, everyone
knows is "Apple Intelligence" ... heh heh heh ... even though they lied).

Paul's link is taking me deeper into today's reality, where apparently the
Copilot+ PC's NPU has to be capable of 40+ TOPS, which I had to look up.

Apparently 40TOPS is 40 trillion operations per second, which is a new
metric to me as of this moment - thanks to Paul's information above.

Minimum PC hardware is apparently the Snapdragon X series processors or
certain Intel Core Ultra and AMD Ryzen AI series processors, and 16 GB of
LPDDR5 RAM (which reminds me that Apple has historically had laughably puny
RAM and now because of AI (Apple Intelligence) they have to actually give
their users a "normal" amount of RAM instead of their bargain basement RAM
that almost all Apple mobile devices have had since the beginning).

a Copilot+ PC apparently also need 256 GB or larger NVMe SSD storage for
the AI data retrieval.

I saw some mention of "Preview" with "Recall" on the older articles I found
in that search. Is Preview perhaps just the older name for Recall?

Apparently, for the r.p.d crowd, there's also something called "Cocreator"
in M$ Paint which generates images based on what's in your Windows activity
list. And in M$ Photos, there's also apparently a text-to-image generator.

No. Because otherwise the security measure of not allowing screenshots
of an app would be useless. And before you rant about this - think about
banking apps or similar use cases, where you don't want anyone just
grabbing the screen content.

Yes, they closed this security issue.

The only option - depending on what your devices support - would be to
connect it with an adapter for USB to HDMI or more common USB to
DisplayPort (which uses USB-C alternate mode for DisplayPort output) and
grab the content using a screengrabber. But of course this only makes
sense, if you need this on a regular basis and are willing to pay for a
grabber hardware.

You want people to help you steal.

Got it.
